STAMP-MQISTENER.

SPECIFICATION forming part of Letters Patent No. 632,967, dated s mer12,1899;

Application filed September 6, 1898. Serial No. 690,254. (No model) H Toall whom it may concern:

Be it known that I, ALBERT NIEDERER, a citizen of the United States ofAmerica, residing at Carlstadt, in the county of Bergen and State of NewJersey, have invented certain new and useful Improvements inStamp-Moisteners, of which the following is a specification, referencebeing had therein to the accompanying drawings.

This invention relates to certain new and useful improvements instamp-moisteners.

The object I desire to accomplish is to construct an apparatus in whicha pad is automatically moistened when the stamp is applied to the pad.

A further object of my invention is to con-.

struct a stamp-moistener that will be simple,

ornamenta and one in which the moisture.

is supplied" to the pad by applying pressure to the same whilemoistening the gum on the stamp. I

In describing the invention in detail referonce is had to theaccompanying drawings, forming a part of this specification, whereinlike figures of reference indicate similar parts in both views, inwhich- Figure 1 is a side view of my improved stamp-moistener, showing apart of the screwthreaded ring broken away. Fig. 2 is a verticalsectional view of the same.

Referring to the drawings, 1 designates the body portion of a receptaclefor the liquid and may be either rectangular in cross section or round;but the preferred construction is round, and it may be made of suitablemetal or hard rubber.

Mounted upon the top of the receptacle 1 is a metallic diaphragm 2,possessing the de sired degree of elasticity so it can be forced inwardwhen pressure is applied thereto and return to its normal position whenthe pressure is removed, as will be hereinafter more fully explained.Secured in any desirable manner or formed integral therewith to thelower end of the body portion is. a coneshaped bottom 3, which isprovided with a screw-threaded aperture to receive the screwthreadedplug 4. In constructing the bottom in the shape of a cone the receptaclecan be easily filled without the aid of a funnel or similar device.Furthermore, it will be impossible to completely fill the receptacle,thereby leaving a space in the upper part of the receptacle filled withair, which is essential to the perfect operation of the device.

I Securedin an aperture in the diaphragm 2 is a feed-pipe 5, terminatingat its upper end in a spout 6,. bent at substantially a right an- "gleto the pipe 5. This pipe projects downwardly to within a short distanceof the bottom of the receptacle and is arranged n'ear the body portion.

Mounted on the top of the cover 2 and spout Q 6 of the pipe 5 is a pad7, of feltor similar material, that is susceptible to moisture. Thispadisheld in place bya screw-threaded band 8, engaging a bead 9, formedon the body of the cone, and is provided with an inwardlyprojectingflange 10, which engages the outer top edge of the felt pad and securelyholds the same in position, as well as the diaphragm 2.

To use the stamp-moistener, the receptacle is first filled with liquid,and by pressing on the felt pad the liquid is forcedfup through the pipe5 and out at the nozzle onto the pad, and by this means the pad becomesthoroughly saturated. In dampening the gum on the stamp the liquid inthe receptacle is ejected onto the pad and is regulated by the pressureon the pad. g I

It will be noted that various changes may be made in the'details ofconstruction withsecured to its lower end provided with an opening at.the apex thereof, of means for closing the said opening, in combinationwith a metallic diaphragm mounted upon the said receptacle, a feed-pipesuitablysec'ured in said diaphragm having its lower end extend.-

' phragm and spout, a removable band secured ing to near the bottom ofsaid receptacle and band for securing the said pad and diaphragm itsupper end bent atright angles forming a in position, substantially asherein set forth. IO spout resting upon the upper face of the dia- Intestimony whereof I afiix lily-signature phragm,-a pad mounted upon thesaid diain the presence of two witnesses.
